SIS Architecture and Modules

SIS Architecture

SIS generates a set of transfer files so data replication can be accomplished through a variety of means. Data replication is based on the "loose synchronization" model, and requires a regular bi-directional transfer of data to keep the databases identical. Consequently, the remote computer almost always has the most current information. Each SIS module can generate and/or apply these files. The preferred method of file transfer is via high-speed modem on a standard telephone connection. MS-DOS diskette transfers are possible but introduce many opportunities for failure. Internet transfers are planned but not currently available.

SIS Modules

• SI Menu: This module is common to all systems. SI Menu auto-detects other modules pesent on the system and enables their functions. Selection of these modules and control of certain system functions are the primary functions of SI Menu.

• Loan Entry: This module is common to all systems. All loan data is available for editing, and may be accessed though a variety of indexes: Borrower Name, Co-Maker Name, Loan Number, Vehicle ID Number, and Current Cycle. A view-only function is available for both SIS' Loan file and its History file. If the Premium Accounting module is enabled, this module provides data entry capabilities not accessible to remote systems.

• Loan Tracking: This module is common to all systems. Regular "processing" is carried out here, and is responsible for generating notices and single interest policies.

• General Reports: This module is common to all systems. Many pre-defined reports are available, such as Borrower List and Daily Activity Report.

• Utilities: This module is common to all systems.

• Account Configuration: This module exists only at Carrera Corp. It controls the parameters that specify the lender's unique requirements.

• Edit Rate Charts: This module exists only at Carrera Corp.

• Edit Refund Tables: This module exists only at Carrera Corp.

• Tape Update: A software interface for mainframe or mini-computer systems allows SIS to synchronize itself to the loan records of the lending institution's own computer system for increased automation. This interface reads files generated by the lender's system, and may be transfered via modem, 9-track tape, MS-DOS diskettes, and eventually, the Internet. Clear advantages of using this feature are automatic addition/deletion of loans and automatic update of borrower information and loan balances.
